To LZZ who/m, it may concern: y

- Be it known 'that I, -GALEB SLADE, of the "city of Troy, inthe county of Rensselaer and State of 'New York, :have invented new 'and useful Improvements in Stoves for lThinning -Coal and also in Ovens and in Boilers; and

I 4do hereby declare that the folllowing is a full and .exact description. ,i

I Ihave yapplied :my improvements to stoves ,made square at the ibase-:having :upright sides ofequal Awidth' and about twice as higfh as v.they are wide-)with a common sunk hearth and sliding dam-per and -a lgrate constructed and managed like .those in common luse with other :coal stoves.

The seat olf the grate consists of aphori- Zontal plate extending to ithe side,- baek and front plates of the-stove with an opening xof the form vand size of the grate in the cent-er.

Fromthe under side of this pla-te a iria-nge is extended down vertically .about four inches to the bottom plate or '-hearth-and vlfiorizontally it is ext-ended around ynear fthe edge of, 'that ,part of the sink which comes within the stove-terminating vertical-ly ltrent on each side even with the forward edge lof the plate to which it fbelongs. This plate and flange are represented in the annexed drawings in Figure I, letters a, b, b, and separately from the stove by Fig'. II. By

means of the forward'termination'of vthe iange it is `made to set snuglyY against' the The back or inner end of Athe sink as well as the cross section oflthef'lfange; behind it as shown in Figs. I and IILis for-l ward of the back plate of the stove far enough to leave room between the plate andi front plate.

flange for an opening thro-ugh the bottom plate as atvc., Fig. III, as an Vinlet Yfor air into lthe space thus left 'between the AHarige and.

outer plates of the stove to be improvedvas an air chamber.

the furnace e, for burning the col-al is placed-the opening in the plate with fthe grate being covered isbyit. =I11-naleft-he furl nace of cast iron and connect it at the topi second air chamber-between which and they chamber that surrounds the flange under- Ths space is partially shown in Fig. I, letters d, d. Uponlthe hori- Zontal plate thus supported by the flange :neath .communications are made by' openings thejlower plate .of the Side naar .the front as Vat it,V it. An opening 1is alsoprovided '-i-n .each side pil-ate as at r2, Figs. VI, VI'I, and

VIII, in fthebaol -plate las seen at 19, iFfig. VIII. Fhese Iopnings'are lnear the top Iof the lupper air chamber fand-are ier the Apurpose of .all-owing' the air as 'it becomes heated 4.to escape into the apartment in which the stove is placed .or .otherwise applied as will hereinafter fbe explained. p

-I .make provision for .a boiler A@I1-each side .of the stove and Ytheir support iI attach a .plate to each side plate extending ont horizontally about Aon a fle-vel with the top .of the furnace to .a distance about `egual .to twice the diameter of the boiler. These for the purpose- Vorf description will be called jthe platforms. )Inorder' #to present ithe boiler tto .the fire-an' opening is yprox'lided in each side plate of the-stove' rfor that purpose-the floottom ofthe opening on a ilove-1 with theplat form and the boilers I make with a' =projecltior'ifo-i'a part othey'essel iftselextendingout ho'riZontally on one `side .to .such distance as that when shoved into the opening it will Vvand of the' projecting part of ftheboiler are adapted toeaeh other. "The` platforms with the Vboilers1in pilac'elover' the' 'furnace are rep'- resented. Fi'g. And. .the boiler separately on a `re'dnced.scale `by ig. V and the side openingen an enlarged Vscale by Fig.

VI, letter y'. Iineaeh .platiiorm a s'inklsprol` vided at the lendl next .to the' stove' occupying a Aspace horiz'ontallly a 'little less than Ythe bottone of' fthe. `external part o' vthe `b'ei'ler when its" projection is .placed over the :furnace.- 'The depth offthes'nk. at the Vsides is aboutv an inchbnt inthe'. center ofzthe .inner edge of the' plate' isje'r'tende'd rdown .so .as "to inclose wtthtn its vlimits 2the opening llo.) in the -sidfe p-llate fthe upper' air chain ber in order that the heated air therefrom may be let into the cavity :formed by they sink under the boiler and thereby assist in heating it. The sink with its depressed section at the center is shown in Fig. VI, 70, Z. The platforms are attached to the stove by means of a projection from the side plates near each edge with a recess in nat-ure of a l socket extending up to a discretionary distance next to the surface ofthe side plate and by providing a corresponding lip or flange from the en d of the platform for each socket it is placed therein and thereby held secure against outward inclination. This is seen at m, m, and a flange from the side' plate as at n, Figs. VII and VIII fitted to the edge of the depressed section of the sink so as to allow it to rest thereupon while the secure section in its bearing against the side plate answers the purpose of a braceby all which the platform is effectually supported in its place, and by raising its outer end is easily disengaged and taken off so as to leave the stove to be used without them when desirable. When either of the boilers are not used the opening for it is closed by a movable plate or door.

The openino for the stove pipe is in the top plate back of the upright part of the back plate, they both being projected out for that purpose as shown in' Figs. I, and VIII. There is also an opening for a boiler at or near the center of the same top plate as is seen in Fig. I.

My improvement in ovens `consists in making them with double bottom sides and top and in using them in connection with coal stoves of the above description and also in the manner of heating them as is hereinafter pointed out.

For the sake of description I distinguish the double plates of which the oven is composed as the inner and outer ovens. They are so apportioned to each other as to leave a space between them for the draft or hot air from the re to pass therein throughout. In order to provide for its entrance an opening is to be made in the bottom of the outer oven surrounded with a shallow flange as a collar fitted in size and form to the opening for the boiler in the top plate so that o n placing the ovenupon the stove the collar will enter the boiler opening and set snugly within it, then by closing the common passage from the re to the stove pipe by a damper such as is commonly used for like purposes the draft or heated air will pass through the boiler opening into the space between the bottom plates of the outer and inner ovens and then up the side and over the top fromthe center of which a pipe is eX- tended as a continuation of the draft to the common stove pipe or chimney as is shown by Fig. VII. In Fig. vIX which is a representation of the oven cn one end in order tc to obstruct the passage.

tection, brick or other material raised above the opening by means of rods of iron placed across it or attached tothe ovens so as not It also make use of the hot air issuing from the upper air chamber to aid in heating a common refluting tin oven which is occasionally placed upon the stove (the boilerV opening being closed) for the purpose of baking or cooking by conducting the heated air into the oven by means of a pipe attached to the opening in the back plate, for which purpose a shallow flange is provided around the opening to receive the pipe. This opening when required is closed and regulated by a damper7 provision beingmade for that purpose as shown in connection with the opening at 7), Fig. VIII. I have a door provided in the front plate ofthe stove for the introduction of fuel to the furnace. These with a narrow horizontal opening for agitating the grate are represented in Fig. VII.

lVhat I claim as my invention and desire to secure by Letters Patent is- 1. The manner of constructing the air chambers between the flange which supports the grate and furnace and the external plates of the stove in combination with the air chamber neXt fabove it in the manner and for the purposes described.

2. The manner'of constructing the platforms and of attaching them to the stove and supporting them in that connection and detaching them from it in combination also with the air chambers in the manner and for the purposes described.

3. The manner of constructing the boilers with the manner of applying the hot air from the air chamber to aid in heating them both in combination with each other and with the stoves of the above description, and also the double oven in combination with the same stovevfor the uses and purposes described.
